Show Desktop Problem which minmizes all the window

sarguna · #1 01-Sep-2006, 04:05

hello Everybody

when we press the Show Desktop symbol in the quick lauch bar it minimizes the application
but i don't want to do so

So i m able to get the message of the first Show Desktop Click or (WindowsLogo + D)
and i do my processing accordingly i.e. minimize it in the system tray

i get the message in WM_SIZE IN THAT

CPP / C++ / C Code:

void CProDlg::OnSize(UINT nType, int cx, int cy) 
{
			
	 if(nType==SIZE_MINIMIZED)
			{
				//minimzed it in the system tray
			}
}

this is wrong as such we are handling the msg after the dialog is minimzed

but when we press it for the second time i.e.Show Desktop Click or (WindowsLogo + D) i m not able to
do the same as it was in the previouly i.e.i don't know how but my application gets popup and is displayed in an unwanted manner.

I am not able to find out which message is send to the dialogbox when the Show Desktop or Keyboard shortcut i.e. (Windows Logo+ D) for the second time.

One thing is clear that the process Shell_TrayWnd program sends message to all the application to minimze
val
/*MinAll*/ 415,
/*MaxAll*/ 416,

accordingly

CPP / C++ / C Code:

static HWND hShellWnd = ::FindWindow(_T("Shell_TrayWnd"), NULL);
if(hShellWnd != NULL)
::PostMessage(hShellWnd, WM_COMMAND, MAKELONG(415, 0), NULL);//for minimizing
::PostMessage(hShellWnd, WM_COMMAND, MAKELONG(416, 0), NULL);//for maximizing

This stuff will minimize all the window

Could u please find out the message so that i could remove the flaw.

Clarification

there are two dialog here one is the main and the other is the floating over the main i.e. for good look only

the floating dialog is modelless dialog

So wat happens is that when we press (Show Desktop ) for the first time

i have written the code in

the message WM_SIZE wParam ==WM_MINIMIZED

to hide the application throught

theapp.HideApplication() and the other i.e. the floating dialog throught ShowWindow(sw_hide)

but when i press the (Show Desktop ) for the second time the thing happens is that only the floating dailog is visible and not the main dialog

Wat i want is

1) either display both the dialog when we press show desktop the second time or hide both of them

Use spy++ to look at all the messages that window gets:
the first time you press show Desktop your window gets:

wm_size fwsizetype:SIZE_MINIMIZED nWidth:0 nHight:0

the second time you press you get:

wm_size fwsizetype:SIZE_MAXIMIZED nWidth:1024 nHight:721
numeric values might differ
